BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a support apparatus with height adjustment, particularly to a selecting structure which is used to control the forward/downward motion, specially applied for adjusting the stature of a liquid crystal display device. [0003] 2. Description of the Prior Art [0004] A traditional support apparatus for height adjustment of a liquid crystal display (LCD) is a kind of mechanism for lifting up/lowering and is applied to all kinds of apparatus with the need of adjusting stature. In particular, the present invention concerns a supporting structure of a liquid crystal display (LCD) device in the contemporary market. [0005] An open loop linkage structure is usually used as legs to support a liquid crystal display device, and the purpose of adjusting the stature of the liquid crystal display device is achieved by adjusting the angle of linkage about an axis. Therein, a liquid crystal display is axially connected to a terminal lever of the linkage structure by adjusting the angle of the liquid crystal display device about the axis. Thus, the displaying direction of the LCD screen is changed. For the need of supporting the weight of the open loop linkage, a rotating resistance of each pivot of linkage increases. Thus, inconvenience of adjusting the rotating angle appears. [0006] According to the foregoing reasons, disadvantages of traditional techniques used for operating a raising/lowering apparatus are improved. SUMMARY OF THE INVENTION [0007] According to a support apparatus with height adjustment of the present invention, a structure used for selecting the up/down motion is provided. [0008] In another purpose according to the present invention, a first body is used to guide a second body and the up/down sliding motion of the second body is selectively controlled by a tenon to avoid disadvantages of the open loop structure. [0009] In yet another purpose according to present invention, adjusting the stature of LCD screen is achieved with a simple structure. [0010] Based on the purposes described above, a second body is installed in a first body of the support apparatus according to the present invention with a sliding way. [0011] The second body is guided in a guiding part defined by an inner space of the first body and is selected an upward and a downward motion by a button which drives a tenon working between a first state and a second state. A spring is respectively connected to the second body and the tenon at two ends of the spring for selecting vertical upward/downward motion of the second body. Furthermore, a LCD screen is located upon the top of the second body. [0012] The objects, feature, and effect of the present invention will be more readily understood from the following detailed description of the preferred embodiments with the appended drawings. BRIEF DESCRIPTION OF THE DRAWINGS [0013] FIG. 1 shows an exploded perspective view of a support apparatus with height adjustment of the first preferred embodiment according to the present invention; [0014] FIG. 2 shows a local cutaway view of the tenon of a support apparatus with height adjustment according to the present invention; therein the tenon is at the first state; [0015] FIG. 3 shows a local cutaway view of the tenon of a support apparatus with height adjustment according to the present invention; therein the tenon is at the second state; [0016] FIG. 4 shows a local cutaway view of the tenon of a support apparatus with height adjustment after coming down according to the present invention; therein the tenon is back to the first state; [0017] FIG. 5 shows an exploded perspective view of a support apparatus with height adjustment of the second preferred embodiment according to the present invention; [0018] FIG. 6 shows a local cutaway view of the damping device in FIG. 5 according to the present invention; therein the tenon is at the first position; [0019] FIG. 7 shows a local cutaway view of the damping device in FIG. 5 according to the present invention; therein the tenon is at the second position; [0020] FIG. 8 shows a side view of a support apparatus with height adjustment of the third preferred embodiment according to the present invention; therein the tenon is at the first state; [0021] FIG. 9 shows an exploded perspective view of a support apparatus with height adjustment of the fourth preferred embodiment according to the present invention; Continue reading about Support apparatus with height adjustment...
